M-OLASSES EVAPORATOR, FILTER, COOLER, AND FURNACE.

SPECIFICATION forming part of Letters Patent No. 236,867, dated January 18, 1881.

Application filed July 17, 1880. (No model.)

To all whom it may concern Be it known that WQ,HEZEKIAH B. WYSONG and WILLIAM H. WYSONG, of North Manchester, in the county of Wabash and State of Indiana, have invented a new and valuable Improvement in Molasses Evaporators, Filters, Coolers, and Furnaces; and we do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this speciflcation, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a plan view of my improved machine. Fig. 2 is a longitudinal section thereof. Fig. 3 is a vertical sectional view of the cooler, and Figs. 4 and 5 aredetails.

This invention has relation to improvements in apparatus for filtering, boiling, and cooling maple-sap, sugar-cane juices, and the like, for the purpose of making molasses, sirup, and sugar.

The nature of the invention will be fully set forth hereinafter.

in the annexed drawings, the letter A designates the furnace, built of masonry, and of suitable length, and having in one end the fire-box a, and at the other a stack, b. The products of combustion pass through the throat c of the fire-box and into a flue, d, formed by a horizontal partition, f,of the masonry, the upward extension g of the side walls thereof, and the bottom of the evaporator B, into the stack through a duct, (1, leading into the same. Below the partition fis a second flue, h, leading to the open bottom of the stack, and provided with two dampers, k and 1, arranged on crank-shafts m n, and capable of being thrown up across the flue, thus directing the products of combustion into the flue h, away from the bottom of the evaporator, when the heat becomes too great.

The evaporator is composed of a metallic pan of suitable depth, divided by transverse partitions 0 0 into a number of boiling-pans, O O O, and a molasses-pan, D. The partitions 0 are provided with vertically-sliding gates p,-that open or cut off communication between the pans, and which are raised or lowered by the levers q, fulcrumed on the edge of the evaporator. The boiling-pan G has a lateral extension, D, reaching out beyond the furnace-walls, and terminating in an inclined or curved end wall, 1, outside of which is a scum-receptacle, E.

The boiling-pans O O O and pan D are arranged relative to the fire-box as follows: The pan 0 is directly over it, pan 0 comes next to pan 0, pan 0" next, and pan D terminates at the stack, being farthest from the fire-box. This pan D has no communication with pan 0, the partition 0 having no gate, and during boiling is filled with water to prevent its being burned out. Extending around the pans G O G" and the extension D of the former are the lateral troughs F G, communicating respectively with the pans O and G by means of the ducts s, leading from them into the same, and closed by suitable valves. As shown in Fig. 2, the damper 76 cuts oii' the heat when thrown up from the pans G O and D, leaving the pan 0 exposed to it, while the damper L simply protects the molasses-pan D.

The cane-juice is delivered from a filtering or straining tank, G, into the side trough, F, whence it passes into the pans G O G, where it is boiled until it becomes a sirup of sufficient thickness. During the boiling the scum rises and overflows into the side troughs, F G, and passes into the pan 0, whence it is received in the extension D. Becoming cool, the scum is raked or drawn up the curved or inclined end 1' of said extension and deposited in the receptacle E. The charge being thoroughly skimmed, the water is let out of pan D and the contents of pan 0 transferred thereto by means of a suitable dipper. This pan being emptied, the contents of the next pan is let into it by raising its gate, and in like manner transferred to the pan D, and so on until all the pans are emptied. The pans (J G C may now receive a fresh charge of juice. while the contents of pan D are being reduced to the desired consistency. This being accomplished, the molasses is drawn off through a cock, 1., falls into a conduit, a, and is carried to the cooler E. This is composed essentially of a number of horizontally-arranged hopper shaped trays, I, having a perforation, u, in their bottoms, and arranged the one above the other in a suitable frame, J. Between the trays are arranged the conical spreaders K. The molasses in the upper tray flows through its perforation or onto the conical apex of the spreader below, and is carried thereby in an outward direction. Falling over its rim, it is received by the next tray, and, being directed inward, passesthrough it onto the next spreader, and so on to the bottom tray. The devious course taken by the molasses causes it to part rapidly with its caloric, so that on reach ing the last tray it is ready for use or for conversion into so gar.

The filterer or strainer is composed of a tank, K, is usually supported upon a stand, and di- Vided by the partitions r 2 into three compartments, L L i. The compartment L is the juice-receptacle, and it communicates with the division 1/ by means of a slot, 2', in the lower edge of the partition 1'. The partition has near its upperedge a gauze-covet ed slot, y. The juice, on entering the division L, must rise to the slot ybetore it can pass intothedivision L, whence it is fed to the troughs F and G through a suitable faucet,aud dirt, grit, and such heavy impurities are here precipitated, while pieces of cane, leaves, and the like are strained out at the gauze-covered opening aforesaid.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a sirup or molasses machine, the combination of the furnace A, having the independent horizontal fines d h, opening the one into the side and the other into the bottom of 5 the stack, the valved openings in the divisionwall of said dues, and a mechanism operating the valves to disclose the openings and close the upper flue, with the evaporator B, seated on said furnace and having the horizontallyarranged boiling-pans (J C G and molassespan 1), substantially as specified.

2. The evaporator consisting of the juiceboiling pans U U C" and the molasses-boiling pan 1), the lateral extension D, having the curved or inclined end wall, 1, and scum-receptacle I), and the lateral troughs F G, communicating respectively with the pans G O G and extension 1), substantially as and for the purposes set forth.

:3. The combination, with a sap-evaporator halving pan C, extension I), and troughs F G, of a filterer or strainer consisting of the tank K, having division-walls .r z, forming compartments L L L, the wall as having slot r at its lower edge, and wall 2 a gauze-covered opening, y, near its upper edge, substantially as specified.

ln testimony that we claim the above we have hereunto subscribed our names in the presence of two witnesses.
